Ok so I drove the Mirage tonight. Ran great but what seems to be happening is it hits about 200 degrees then when I turn it off I get antifreeze coming out of the radiator overflow hose. Does this mean I have air trapped in the system? I don't have a 'purge' tank. It ran fine before I opened up the cooling system. I replaced the hoses and had the radiator gone through. Now I keep getting this same issue.
